npm start npm ERR! Missing script: "start"

Question

Getting this error with "npm start." Similar questions have their problems solved by reconfiguring package.json, so I tried changing mine:

 "scripts": {
        "start": "node app.js"
      },

but still got the error. Could it be because I used webpack?

My package.json file:

{
    "name": "webapp",
    "version": "0.0.0",
    "description": "",
    "keywords": [],
    "scripts": {
        "start": "webpack-dev-server --mode production",
        "build": "webpack --mode production",
        "deploy": "gh-pages -d dist",
        "test": "cypress open"
    },

@skara9 You're right. The problem was I was not in the same directory as package.json.

so I navigated to the right directory and tried npm start again and got

> webapp@0.0.0 start
> webpack-dev-server --mode production

CLI for webpack must be installed.
  webpack-cli (https://github.com/webpack/webpack-cli)

We will use "npm" to install the CLI via "npm install -D webpack-cli".
Do you want to install 'webpack-cli' (yes/no): 

When I said yes,

What could be the problem this time? Thank you so much!
